Question

I have 3 viewController classes, A, B and C.

From class A, I push and present class B and then from class B I push and present class C. All classes have delegate protocols defined, so

• b.delegate = a
• c.delegate = b

Now I am inside class C, but I need to run a method from class A.

What is the best way to call that method? I mean the best practice.

I can imagine declaring this on B

- (BOOL) myMethodOnA {
// this method on B will run the method on A and return it to C
   return [delegate myMethodOnA];
}

but this sounds to me like a bad solution.

Any suggestions?

thanks.

Answer 1

I might miss something obvious but shouldn’t this work?


[c.delegate.delegate myMethodOnA]


Also get into the habit of using accessors (make sure you don’t take ownership of delegates). ARC makes this so much better.
